IMPROVEMENT IN BINDERS ATTACHMENTS FOR HARVESTERS.

Specification forming part of Letters Patent No. 142,8?}, dated September 16, 1873; application filed May 31, 1873.

To all whom itmzafy concern Be it known that I, WAsmNGToN L. SAN FORD, of Ashton, in the county of Lee and State of Illinois have invented a new and Improved Binding Attachment to Reapers, of

which the following is a specification:

My invention relates to certain improvements in binders for harvesters, as hereinafter described, and specifically indicated in the claims. v

Figure 1 is a side elevation of my improved binding attachment. Fig. 2 is a plan View,

- and Fig. 3 is a detail view of one of the wheels of the operating-gear.

Similar letters of reference indicate corresponding parts.

A represents a hollow cylinder, or it may be air opezr-fiame, long enough to receive the longest grain, and large enough for receivingsuflicient loose grain for a gavel in one part, and having another part iii which to compress it. It is attached by a s uitable supporting frame, 13, to the side of a reag'eriu such manner that the endless elevator therehf wi l deliver the grain into the opcningU, nea the top, where there is a shaft,'D, provir led with.

curved teieth, to. adapt it to clear 1; e grain from the elevator, and press it downward and compact it in the receiver.

It will be seen that to thus operate the ro- 'tation must be in a direction to bring the bow or curve of the wire teeth forward, so that they shall come first in'contact with the grain: At the bottom of the cylinder is a shaft,

.E, with teeth or arms F projecting upward nearly to the center, to retain the falling grain in the side where it falls until a quantity sufficient for a gavel is obtained. There are also fingers or rods G projecting downward from the top cross-bar H, to guide the grain as it falls-from the elevator to the side, where it accumulates for'the gavel. I represents the stationary compressing-arms. They are attached at one'end to the bar J, and curve upward therefrom, as shown in Fig. 1,

space M under the curves of these arms, forcompressing it to be bound. The movable compressing-arms N are mounted on theshaft L. This shaft has a pinion, O, and a wedgeshaped cam, P, on one end, and in connection with this pinion and cam is a wheel, Q, having a sufficient number of cogson its periphquired. The wheel Q, has a portion of its thickness removed along the toothed part, I and a little beyond, as indicated at '1, so that the. cam which is arranged alongside of the pinion can turn without obstruction by the wheel Q, while the teeth of the latter are in gear with the pinion.

While the gavelis accumulating, the compressing-arms N are holding the one being bound, and after releasing it theyare swung upward to the left, over to the right, downward onto the grain, and then up again to the left until arrested by the pressure of the grain brought up by them under the arms Iy'and the toothed part of thewheel Q escapes from the pinion, when they come to a rest, and are held by the smooth face of the wheel acting on the cam P. The extent of the compression of the gavel is regulated by springs U and auxiliary compressing-arms V, fixed on the arms I. It is also further regulated by the bar J, to which the stationary arms are attached, being arranged to rise to some extent under the control of springs WV. The arms or plates V have another important function, in that they act to cast the bound gavel down and out of the cylinder speedily, which is especially necessary when the gavels ar'e'light, in order that the rake may the sooner revolve and save time for-the binding. The bar J is also arranged so that, in case a gavel does not discharge, and another is forced into the binding-space, it will, after rising to a certain ,height, lift the lever W, and automatically throw the wheel Q out of gear, and thus prevent breaking the machine.

When the'arms N push the grain up into the stationary compressing-arms, the arms F on shaft E are swung down, first by the wrist d acting on the arm f tostart them, and then by the pressure of the grain on them, so as to partly bridge over the escape-passage Xbetween shaft E and rod Y, through which the bound' the grain to prepare the bridge by which it may pass up to the compressingarms. When the bundle is thus compressed in the space M. the band is put round it and-fastened by the attendant who stands on the platform b. The

shaft L is cranked at e, in such manner as to provide space for the attendant to pass his arm between it and the bundle for passing the band around the latter. When the arms N have arrived at the limit of the movementin compressing the bundle, they have passed beyond the ends of arms F and freed them, so that they are forcedback immediately by the springarm f to the position for retaining the grain falling from the elevator. Aspring,'g, prevents them from being thrown too far back. The

arms Z are also released before the armsN stop when compressing the gavel by the escape of the wrist-pin d from the lever a, so that they fall back, and, thus the space'X-for the escape of the bundle is opened to let it fall to the ground when bound, Thebundle is released from the arms N when in the rotation of the wheel Q the front portion of recess T comes to tlie cam Pand releases it from the faceof the wheel,so that it is free to turn. Theweight of the arms N andthe bundle then turns them back to the position represented in Fig. 1, and the bundle escapes. At the same time lever (1. falls on the wrist-pin d, and by its weight holds the teeth against the grain so they cannot'swi'ng, as they otherwise might by the jarring of the machine. The platform I) is made verticallyadjustable on the standard It by the hanger t and notches j, to adjust it to suit the 7 height of the operator. A back-rest, k, is arranged on the top of the standard h, to which the operator can secure himself by a strap to guard against being thrown off by 'thejolting of the machine. I is a trough for carrying the bands with which the bundles are bound. The

, clutchisshifted by the levers m and link p.

The isk K and stationary compressing-arm I at one side of the place where the binder passes the band around the bundle are attached to their respective supports, so that they can be shifted on them to vary the width of the space.

Bands or hoops K i may be used instead of these disks for keeping the grain from the shaft L as it is carried up into the compressing-space. If the grain is in sufiieient quantity to obtain enough for a gavel during one revolution of wheel Q it will be kept continuously going and not thrown out of gear, and the gavel will be bound while the smooth part of the said wheel is passing the pinion; butin case it is light said wheel can be thrown out untilenough has accumulated.

Having thus described my invention, I claim as new and desire to secure by Letters Pat-v cut-- I. The arrangement of compressing-arms'I and bar-J with the shippingdever n, for automatically throwing the rotating compressin garms out of gear, substantially as specified.

2. The shaft D, having curved arms, and arranged inthe upper open portion of the cylinder, in combination with the'rods G,Vfor the purposeof packing the grain, as set forth.

3. The retaining-arms F, combined with the receptacle A and the movable compressing- 'arms N, substantially as specified.

- 4.. The combination of retaining-arms Fand arms Z with the receptacle andthe compressing-arms, in the manner described, for conveying the grain over the discharging-space.

5. The wheel Q pinion O, and cam P, constructed and. arran ged in the manner described, for operating the movable compressing'arms, holding them during the binding of the bundles, and finally discharging said bundies.

6. The stationary 'arm I and the disk K at 'the space for presenting the bands, arranged adjustably on their supports for varying the space, substantially as specified.

7. The support J of the stationary compressing-arms, arranged to yield to the action ofkthe movable compressing-arms and controlled by springs, substantially asspecified.

8. The arm a, relatively arranged with the wrist-pin d to hold teeth N against the grain and prevent them from vibrating, substantially as specified.

9. The binders stand, arranged adjustably on the guard-standardh, asspecified.
